Appiicatin filed March i4, 1927. seal no; 175,342.

This invention, generally stated, relates to an auxi'liaryjvater heaterarranged toV be supported within the fire pot or combustion chamber of afurnace, stove, or gas heater, y and has more especial relation tothetypeV factured under the patent aforesaid too quickly passes tothe'element to be heated, as for instancea radiator, with the resultthat-'full efficiency of the auxiliary water heater is not obtained;

The leading object ofthe present invention is "to overcome thisdisadvantageous feature and provide fan auxiliary water` heater of thecharacter stated in which the radiating hollow branches ofthe Iauxiliarywater heaterare so arranged that cooled water as returned to theauxiliary water heater is battled, deflected, and retarded sufficientlyto beconiemore oi' less heated from the furnace,'stove or gas heaterprior to its being` delivered to vthe yelement to'be heated,

Y Y s pipe having screw-threaded relation with the upper nipple 2. ,Theupper endof pipe Y as for instance a radiator.;l y l Y Y n Afurther'object'of thepresent invention resides iii the provision of vabaille plate hav'- ing radiating extensions, .the general configurationof the baffle plate being somewhat star shaped,ithe extensions of saidbattleA plate eitherv having the edges thereofintegral with or closelyfitted againstat least a portion of the side walls of each of Vthcradiating branches'of the heating chamber of said auxiliary waterheater.

lVitli these and. otherobjects in view, the invention consists of thenovel construction hereinafter described and finally claimed.

The nature, characteristic featul'res Yand scope of the invention willbe morel fully understood from the following` description taken inconnection with the accoinpanying drawings forming part hereof, and i inwhich: l i

For the purpose ofzillustrating.my invention Il have shown inl theyaccompanying drawings one form thereof which fatpresent preferredby ine,since the samehas been 'Y found"inpracticeqto give satisfactory andreliable results, .although 'it is to. ,be under,-v stood that thevariousinstrumentalities ofA which my invention yconsists .can bevariously arranged andorganized andthatmmy invention is notlimited totherprecise arrangement .and organization .of the instrumentalities. ashereln shown :and described.

Referring now to the drawings in detail,`

the reference numeral' 1 .designates a. water heating chamber,,preferably formed ofy cast inetaland provided-top andbottom with in`ternally threadednipples 2-and 3 respectively. Thesenipples 2 and 3 arecentrallyarranged andV radiating therefrom yare a plurality of hollowbranches Li These hollow branchesA 'i 4fl in Veffect .providea generallystar shaped water heatingchainber as best seen in Fig. 3.`

supported by a pipef5,the .lower endl ofy said 5 carries a connect-ion Gfor the passageot heater water to a suitable heating element` as aradiator, not shown iii the drawings. The bottom of the water heatingchaniber 1.

as shown in Fig. 1, is closed by a plug 7. Ar-

ranged witliin pipe is a pipe S connected for the return of cooled waterto the water heating element 1,' the ksaidpipe 8 being spaced from thewalls of pipel 5. The pipe 8,1as clearly shown, projects into theheatingv vextensions 9 of the baille plate extend Well along therespective hollow branches and p formed integral with the side wallsofthe-hollow branches or closelyfitted Vagainst the'side walls thereof,as is very clearly shown in Fig. 3. This arrangementof parts provides abaffle plate of maximum area so that cooled water being returned throughpipe 8"is balied or retarded temporarily so that the said water may bemore etliciently heated than it is in the auxiliary water heatermentioned in the patentafore said. Retarding or battling the cooledwater as returned to the water heating chamber so that said water may beadditionally heated adds materially to the eiiiciency'of the auxiliary.water heater since when the water is additionally heated as by mypresent device, the heater water passing to connection 6 obviously hasthevtendency to bring the waterpassing through pipe '8 to a highertemperature than ispossible in the aforesaid patented device.

If it is desired to extend the heating surface of tlie heating'chamber1, a lpipe or water leg 10 may be screw-threaded into the lower nipple3, as clearly 'shown in Fig. 2, anda plug 11 secured to the bottom ofpipe l0. In this' case an extension 12 is secured with respect to pipe 8so that the water being returned from a radiator is directed to thebottom of the water leg 10. v

In Fig. 5, a furnace 13 is shown. which may be of any particular typeand to which my novel form of auxiliary water heater is applied.

It will be noted in the connection that all of the ligures illustratea." Water heating chamber in which the baille plate extensions 9terminate short of the outer ends of the hollow branches of the waterheating cham* ber. Thus, considered in plan, as clearly illustrated inFig. 3,' relatively circular openings 14 are provided in each hollowbranch ofthe ywater heating chamber for the vpassage of water tothe pipe5. p

`t will now be apparent? that I have devised a novel and usefulconstruction which embodies the features of advantage enumer ated asdesirable in the statement ofthe in*k vention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesat- Vlsfactoryl and reliable results, it' is to be un,- derstood thatthe same is susceptible ofl modification in various particulars withoutdeparting from the spirit or scope of the invention or sacrificing anyof its advantages. l

Having thus described niy invention, what I claim as new and desire tosecure by Letters Patent is: Y Y 1. A device of the character stated,comprising a water heating' chamber having a branches and closelyAengaging'- the side YwallsV of said branches, an inlet pipe for convey-Y ing eooledwater to thebottoin of said Ichamber and an outlet pipesurrounding saidtirst.

mentioned pipe for the. exit Yof heated water.

2. In a device of the character stated, comprising` a water heating`chamber having' a plurality of' radially extending' hollow branches, abaffle plate arranged within said chamber, said plate having extensionsequal in number to and coincident with said hollow branches, saidextensions extending into and terminating short of the outer ends of'said branches and closely engaging the side walls of said branches, theends of said. extensions andthe ends of said branches, considered inplan, forming' relatively circular openings, an

inlet pipe for conveying cooled water to the e bottoni of said chamber,and an'outlet pipe surrounding said first mentioned kpipeA for the exitof heated Water;
